Appendix S2 Detailed Results from Species Distribution Models Appendix S2 Detailed results from species distribution models. Considering test data for models with climatic or geographic variables, respectively, three and one species (1.7 and 0.6%) had AUC values lower than 0.5, while 52 and 68 species (29.2 and 38.2%) had AUC values lower than 0.7 (Table S2.1). Comparing taxonomic groups, for models with climatic or geographic variables respectively, only three and one arthropods species (4.5 and 1.5%) had AUC values lower than 0.5 (for models considering climatic variables – Crotchiella brachyptera, Drouetius borgesi centralis, Megaselia leptofemur – and geographic variables – Orchestia chevreuxi – respectively). For climatic predictors, the highest number of AUC values lower than 0.7 was in arthropod species (19 species – 28.8%) while for geographic predictors it was in vascular plants (26 species, 53.1%).

  • Patterns of Colonization and Species Distribution for Azorean Arthropods: Evolution, Diversity, Rarity and Extinction

The target group are the arthropods, and the main habitat the Laurisilva, the Azorean native forest. Diversification of Azorean arthropod species is affected by island age, area and isolation. However, results obtained for over a decade show that distinct groups are differently affected by these factors, which has lead to the extreme diverse distribution patterns currently observed. Spatial distribution of arthropods in each island may be interpreted as caused by a typical “mass effect”, with many species following a “source-sink” dynamics.

The consideration of both these characterisation domains allows the definition of a homogeneous system of reference (the stable characteristics) with which every possible land use pattern can be compared through the use of common evaluation algorithms.

  • SJO BIOSFERA EN.Pdf
    MESSAGE FROM HIS EXCELLENCY THE PRESIDENT OF THE GOVERNMENT OF THE AZORES In a dispersed territory like the Azores, particularly in the smaller settlements, it is essential to encourage sustainable development since it is the route to economic progress, social cohesion, quality of life, and the preservation of natural heritage. In good time, the Government of the Azores has set inhabitants of São Jorge the challenge of jointly drawing up an application to UNESCO for the Fajãs de São Jorge to be designated a biosphere reserve. Right from the start, this process has been a very inclusive one. Indeed, only by being so can it succeed as it is up to individuals, communities and institutions to choose the foundations for their own development. The public authorities are responsible for establishing the conditions required for this development by enhancing knowledge of our existing natural and cultural assets, improving the conservation of these assets and fostering landmark projects that may serve to catalyse the aims of the Man and Biosphere (MAB) programme. The Fajãs de São Jorge are an example of a balanced but not always peaceful relationship between human beings and nature. As such, they offer clear evidence of perseverance and tenacity and are unique repositories of ways of life, landscapes and biodiversity that must be conserved and enhanced. The biosphere-reserve designation will confer international renown on São Jorge, placing the island and its fajãs in a network comprising over 600 sites around the world. It will also add economic value to the products and services produced there by allowing them to display a UNESCO seal of quality.

  • Azores): a Protected Quaking Bog Habitat Cândida Mendes1,2 and Eduardo Dias1
    Acta bot. bras. 23(3): 812-819. 2009. Characterisation of Sanguinhal Mire, Terceira Island (Azores): a protected quaking bog habitat Cândida Mendes1,2 and Eduardo Dias1 Received: June 27, 2008. Accepted: December 3, 2008 RESUMO – (Caracterização da Turfeira do Sanguinhal, ilha Terceira (Açores) um habitat protegido de turfeira ondulante). O Arquipélago dos Açores no Atlântico Norte é uma área importante em biodiversidade, rica em espécies e habitats raros em estado selvagem. A turfeira do Sanguinhal foi originalmente uma lagoa que evoluiu por paludificação para um habitat de turfa. Esta localiza-se na Rede Natura 2000 (União Europeia para a Proteção da Natureza e Biodiversidade, Directive do Conselho 92/43/EEC de 21 de Maio 1992 sobre a concervação de habitats naturais e da fauna e flora, Diretiva de Habitat Anexo I(b) habitat 7140) da Serra de Santa Bárbara e Pico Alto e é um bom exemplo de um tipo de turfeira de bacia, descoberto pela primeira vez em 1998. Este trabalho provê informações iniciais sobre a flora, as comunidades vegetais, a estrutura, as caracteristicas químicas da água e o regime hidrológico de superfície. Foram identificadas 41 espécies vegetais, incluindo 6 espécies do género Sphagnum, e 10 espécies de plantas vasculares endêmicas, forma identificadas oito comunidades vegetais. A profundidade máxima de turfa é de 2,5 m. A turfeira recebe água superficial de suas margens, além da precipitação interceptada e da névoa. Depois das chuvas, a água é drenada por vários pontos da turfeira onde o placic se rompeu. O pH e a condutividade das água foram medidos tendo-se verificado algumas tendências.

  • Vegetative Propagation of the Endangered Azorean Tree, Picconia Azorica

MOREIRA, L. SILVA & M. MOURA Martins, J., O. Moreira, L. Silva & M. Moura 2011. Vegetative propagation of the endangered Azorean tree, Picconia azorica. Arquipelago. Life and Marine Sci- ences 28:39-46. Picconia azorica (Tutin) Knobl. (Oleaceae), commonly named “pau-branco”, is an endan- gered tree endemic to the Azores. Vegetative propagation may be important for the preser- vation of this species, particularly in depauperate populations, with low seed set. The ob- jective of this study was to evaluate effective techniques for the vegetative propagation of P. azorica by rooting of stem cuttings or by air layering. Rooting substrate, IBA concentra- tion, and the portion of the area of the terminal leaf pair kept on stem cuttings, when tested in early spring (semi-hardwood cuttings) and autumn (hardwood cuttings) failed to produce any rooted cuttings. In contrast, air layering performed in the autumn on lateral branches of adult trees was successful. After 12 months, air layers treated with 5000 ppm of IBA in talc achieved 65% rooting, while those treated with 2500 ppm IBA or without growth regulator only attained 41 and 28% rooting, respectively. Our study indicates that P. azorica is rela- tively easy to propagate by air layering. This method could be used to restore natural popu- lations of P. azorica when seeds are not available or plant competition impairs natural re- generation.
